Two recent pieces by Matthew Schmitz of First Things that are worth a glance: One in the UK Catholic Herald, and another in the NYT, (what? In the NYT???) on what is colloquially called the "Latin Mass," more formally, the "Extraordinary Form" or the "usus antiquior" or less technically correct, the "Tridentine Mass."
What I find fascinating is the absolute horror, vehement opposition, and worse, that the ancient Mass elicits amongst the clergy, particularly older clergy. I've seen this first hand.
